ELECTRICAL APPARATUS.

SPECIFICATION forming part of Letters Patent No. 381,856, dated April24, 1288.

Application filed Nevembcr 23, 1886. Serial No. 219,594. (No model.)

tion of the same, reference being had to the accompanying drawing, whichforms apart of this specification.

My invention relates to an improvement in electrical apparatus, and moreparticularly to means for lengthening and regulating the in-' tervalbetween the vibrations of an automatically vibrated armature, the objectbeing to control an armature so vibrating, so as to employ it as amotor.

With this end in View my invention consists in a regulator forlengthening and controlling the interval between the vibrations of anautomatically-vibrated armature.

My invention further consists in certain details of construction andcombinations of parts,- as will be hereinafter described, and pointedout in the claims.

The accompanying drawing is a plan view of one form which the regulatormay assume.

The magnet A, armature B, anchor-shaped pallet C, adjustableretracting-spring D, and spur-wheel E are of ordinary construction, thearmature being secured to the stem of the pallet. A platinumtippedelastic wire, F, is also secured to the said stem and extends within therange of a platinum contact-pin, G, located in the rim of abalance-wheel, H, mounted upon a balance-staff, I, carrying ahair-spring, J, adjustable in tension in a split post, K, as shown.

The circuit is made from the battery L to the magnet A, anchor-shapedpallet C, contact-Wire F, pin G, balance-wheel H, balancestaff I, andthence to the other pole of the battery. The closing of the circuitenergizes the magnet, which then attracts the armature, drawing thepallet swiftly toward the balancewheel,which rotates with thecontact-wire and pin in contact until the armature and pallet reach theend of the stroke. By this time the balance-wheel has acquiredsufficient momentum to keep on rotating, carrying the pin away from thewire, and hence interrupting the current through the magnet, whioh,beingdemagnetized, releases the armature, which, with the pallet, is thenretracted by the adjustable sprinfi: Meanwhile this double motion of thearmature has advanced the spurwheel a tooth. As soon as the momentumimparted to the balance-wheel by the pallet is expended, the hair-springat once reverses the wheel and brings the pin in contact with the wireagain, whereby the circuit is closed, the magnet energized, the armatureattracted, a quick movement imparted to the pallet,and the balance-wheelrotated to break the circuit, hold it open for an interval, and thenclose it again, and so on.

It is to be noted that the pin G, forming a movable contact-point, ismoved in an unobstructed are, so that however much the impetus impartedto the wheel, and hence the arc of vibration, may vary underfluctuations of the operating current, the time of vibration will alwaysremain constant under the wellknown law. The interval between the makesand breaks may be determined and regulated by adjusting the hair-spring,the retractingsprings, and in other obvious ways. By thus lengtheningand regulating the interval be tween the vibrations of anautomatically-vibrated armature such vibrations may be employed for andconverted into motive force, whereas they have not hereto been availableon account of their rapidity and the brevity of the interval betweenthem.

Obviously the regulator may assume many forms, nor is it limited to abalance and spring arranged to secure an interval, which may be securedby the employment of apendulum,or

the employment of the equivalent of either. Nor is a retracting-spring,as herein shown, necessary. Its place may be taken by gravity or anothermechanical arrangement. I would therefore have it understood that I donot limit myself to the exact construction and arrangement of partsherein shown and described, but hold myself at liberty to make suchchanges and alterations as fairly fall within the spirit and scope of myinvention.

Having fully described my invention,what I claim as new, and desire tosecure by Letters Patent, is-

1. An automaticallyoperated armature car- ICO rying a contact point, amovable contact point normally in contact with that of the armature andmounted or suspended to be set in virtually free motion in anunobstructed are by the impetus derived from the effective stroke of thearmature, which thus breaks the circuit between the two points, thecircuit being re-established when the movable point returns again to itsposition of contact with the contact-point of the armature,substantially as set forth.

2. An automatically operated armature carrying a contact-point, amovable contact-point normally in contact with that of the armature andmounted or suspended to be set in virtually free motion in anunobstructed are by the impetus derived from the effective stroke of thearmature, which thus breaks the circuit between the two points, and aspring to restore the movablepoint to its normal position after itsimpetus is spent, substantially as set forth.

3. An automatically-vibrated armature carrying a eontact-point, and abalance wheel carrying a contact-point normally in contact with that ofthe armature and mounted tobe set in motion in a wholly unobstructed areby the impetus imparted to the wheel by the stroke of the armature,substantially as set forth.

' 4. An electrical apparatus having a con taetpoint suspended or mountedfor move ment in an unobstructed are, and an auto matieally-operatedarmature adapted to move such point so as to. break a circuit which isclosed when the point returns to its normal position, substantially asset forth.

5. An automatically-vibrated armature, a contact-point carried thereby,abalance-wheel, a pin carried by such wheel and normally in contact withthe point carried by the armature, and a spring for reversing the wheeland re-engaging the point and pin after they have been separated by theactuation of the wheel under the stroke of the armature, substantiallyas set forth.

6. An automatically-vibrated armature, a pallet connected therewith, acontact-point connected with the arinature,a balance-wheel, acontact-point carried thereby and normally in contact with that carriedby the armature, the two points being separated to break the circuitunder the stroke of the armature, and a spring connected with thebalance-wheel to reverse it and re-engage the points after the momentumto the wheel has been spent, substantially as set forth.

In testimony whereof I have signed this specification in the presence oftwo subscribing witnesses.
